Abstract

Un besoin d'informations mobile est caractérisé par des exigences spécifiques qui dépendent en général de chaque emplacement. Afin de tenir compte de ces exigences et d'éviter un surplus d'informations qui entrave l'accès aux informations importantes, une concentration ciblée sur des données localement importantes est nécessaire. La présente invention concerne un procédé pour transmettre des données, un système de transmission de données, ainsi qu'un terminal radio et un émetteur de contenu. Cette invention est caractérisée par une infrastructure autonome et par une très grande indépendance des points sensibles grâce à l'unidirectionnalité de la transmission de données. La concentration sur les données importantes est principalement réalisée par l'adaptation prévue de la portée de l'émetteur. Les données sont transmises et demandées dans une structure latérale définie. Le système de transmission de données, l'émetteur et le récepteur sont réglés de manière ciblée à ces conditions générales. Le procédé selon cette invention est entre autres adapté à un usage dans des moyens de communication mobiles en raison de sa flexibilité.
